Electron-impact excitation to the 4p(5)5s and 4p(5)5p levels of KrI using different distorted-wave and close-coupling methods - art. no. 052710

Electron-impact excitation of the 4p-(5)5s and 4p(5)5p levels of Kr I has b een investigated in detail by calculating cross sections using distorted-wa ve and close-coupling approaches. The results are presented from the excita tion thresholds up to 50 eV incident energy. They are contrasted among the different calculations and compared with other theoretical predictions and experimental data. Significant disagreement is found with many of the recen t experimental data of Chilton et al.
